There are many ways to layout your E10 disks... is anyone using JBOD for Exchange 2010 within a DAG?
Is the failure of a node completely transparent to the end user?
Are transactions ACID compliant? .. in other words will an in-flight transaction be repeated/resumed on the failover node?
I'm aware RAID could be used within a JBOD, but some people here may not know that Microsoft has a proposed raidless-JBOD architecture with Exchange 2010 for the mailbox role. In the event an array or node fails, the CAS server will failover to a different server hosting a replica of the JBOD data.
I'm only interested in answers that take into account JBOD with the new DAG concept, does it work in the real world, and is anyone doing it.
